WO'UND PACKAGE .AND METHODIOF vPRVIODYUCING THE SAME.

"'Applicanon'mea November e, 192e. seriainallassli'.

Tubular packages which vare intended kto be `dyed by alternate endwisecompression and expansion in Vthe dye bath, asby the Well known Franklinprocess, vhave heretofore been woundof approximately the same density'throughout, with' the exception of Vthe s ends of the package Which werenecessarily Wound harder because of the greater pres- Y sure ydue to thereversal of the Winding and consequent accumulation of the yarn at saidends.

portions were endwise compressed in the process of dyeing, the endsbecame still harder and obstructed the thorough penetration of the dye,With the consequent result of an uneven` dyeing of the package.

Theobject of my inventionisl to produce va tubular package which will becapable of being evenly dyed throughout. To accom-V plish this objectVthe package is Wound so that it Will normally be of greater density atits middle portion than at its end portions and, when compressed endWiseinthe dyeing process, Will be of substantially the same ydensitythroughout. This result is obtained 'by providing means for somoving the traverse guide for theV yarn that the movementk of the guidewill be gradually increased as V 4the guide moves away from the middleportion to the limits of its travel and Will be gradually 'decreased asthe guide moves from the limitsof its travel to the middle portion.

the traverse guide 6 is is movedlfrom the limiter the' middle' per:

tion of its travel, so'that the package Willf'be Wound With'agreateridensity at itsmiddle portion'tha'n at Aits ends. 1

In the present instance this variablemove ment of thetraverse guide 6 isaccomplished n by so vshaping the groove .71 of the guide reciprocatingcam 8 that'it Will have gradually increased pitches .from its centerlto.-

Ward both ends, thereby causing thetraverse guide to move faster at'bothextremities of its 'traverse Vand slower at kits mid-traverse `The Woundpackage Vvvill thus normally have a greater density'at-Iitsmiddleportion plished with the ends softer than the middle thereof. Ys

I have found that a, package Wound as above described will, Whensubjected toV the alternate endvvise compression and expansion in thedie bath,evenly andl rapidly ab- L sorb the dye, thereby .ensuring abetter product in a lesser time than has been possible stantially thesame diameter from end to endv and having a harder middle portion andsofter end portions. t
